论文摘要
我们考虑了中微子质量矩阵的质地，其特征是一个消失的$ 2 \ times2 $扣子。我们在现象学上和分析上分析了所有六种可能的模式，并表明所有非符号的模式都能适应实验界限，而单数模式仅允许四种倒下的层次结构类型纹理。然后，我们通过将其直接或间接地将其与零质量联系起来，对此纹理进行一些可能的实现。
We consider a texture for the neutrino mass matrix characterized by one vanishing $2\times2$ subtrace. We analyze phenomenologically and analytically all the six possible patterns, and show that all non-singular ones are able to accommodate the experimental bounds, whereas singular patterns allow only for four inverted-hierarchy type textures. We then present some possible realizations of this texture, within seesaw scenarios, either directly or indirectly by relating it to zero-textures.
